To the point: Sony Xperia J is only equipped with 4GB internal memory in which it's only has 2GB user storage availability. With the Android Ice Cream Sandwich OS and also 4.0 inches display TFT capacitive touchscreen, I believe that you'll must download many applications and games available on the Google Play. It's of course need quite huge storage.

Moreover, Sony Xperia ST26i / ST26a (series name of Xperia J)has 5 Megapixel camera, in which you'll need some huge memory storage to store you saved videos or photos. That is why the 32GB microSD external card is designed for additional storage (not included in package). And after you got this external memory, you need to insert it on the phone to make it works.

We are here to give you those explanations and guidance. In addition, Xperia J supports for 3G HSDPA networks up to 7.2 Mbps and HSUPA up to 5.76 Mbps. You might bought this phone without mobile provider carrier, in which you need to insert the SIM card of your carrier manually. We also provide the instruction to insert the SIM card on this Xperia J: uses mini SIM type.

Get the phone in rear panel view. Then see on the left-bottom side of the phone. There is a opening gap that you can use to remove the back cover casing of Sony Xperia J. Just use your tip of finger (thumb / forefinger) then insert to the gap and firmly lift up the battery cover slowly. Remeber that the other hand must hold tightly the phone body but without grip the back cover. Whenever the left-side bottom cover is opened, then continue to detach the cover from side to side until it's fully removed.

After you able to open the battery cover, now you can see that inside the cover, there are a sim card slot, a memory card slot and installed battery on its compartment. To be able on inserting the mini SIM card on its slot, and also inserting the external storage card, you need to remove the battery first.

Removing the battery can be done just using your tip of forefinger to lift up the battery from its compartment at the opening cave at the bottom side of the compartment (pictured). Lift it and remove it.

With gold-colored contact is facing down and the cut-edge of the sim card is placed in bottom-right position, you can just slide the sim card into its card slot until it reaches the end of the slot. You can do the same process for microSD card: slide the card to its slot with gold-contacts face down until it "locked".

To remove the sim or microSD, you can do the opposite: use your tip of forefinger or thumb on to firmly "grip-slide" then slide it out from the slot. Remember before you remove the memory card, you must umount it first via storage settings and of course, you have to turn the phone off.

Now you can assemble the battery back to its compartment, and then firmly reattach the back cover casing: align the back cover to the phone body side, then push it downward side to side until it firmly attached. You might hear a clack sound in the process.

Note: the difference between ST26i and ST26a only on the frequency of its data network technology. The 26i for Global; the 26a for America

The Li-Ion battery on the Sony Xperia J uses 1750 mAh capacity. In which, the battery should be charged before you wanna turn the phone for the first time. It might that the battery has not enough power to give the Xperia J electricity, that why at least the battery need to be charged for about 30 to 60 minutes.

Connect the USB cable on microUSB side to the Phone USB charging jack; connect the USB side to the Power Adapter; and finally plug the Adapter to Power Electricity Outlet. That how you can charge the battery of Xperia J in "normal" way. Alternatively, just connect it directly using USB cable to Laptop or PC. Although the charging time take longer than the "normal" way, but you still able to make the battery "charged".

Charge Battery, Power On Sony Xperia J ST26

Green, Red and Orange LED Lamps would indicate the charging process. Whenever it Red, ASAP, you must charge the phone; whenever it Green, immediately remove the charger (means the battery is full); and the Orange is the level of the battery in "enough" position or it being charged.

Now after you install the sim, assemble the battery, charge the battery and microsd (optional), it's time to turn it on for the first time. Just press and hold the power button available on the right side of the phone (pictured) until the phone vibrates (take about 2-3 seconds). Just wait and do the rest (may need to insert pin, choose default language, time etc).

In case you got bored with Xperia J and wanna sell it to other person and change to the new phone that you like, it's better that you remove all the data and make the settings back to its factory original default. To do that just go to Settings > Backup & reset > Factory data reset > Reset phone > Erase everything.

The Hard Reset (alternative name for Factory Reset) can be applied also to make you phone works normally like it original when you noticed that the Xperia J got freezes or the touchscreen stop responding too often.
